To remove a dock icon.. click on the icon and hold down your mouse button.. then drag it off of the dock and then let it drop to the eternal fires below!

To unninstall programs, find the program directory that you want to uninstall, click on it, hold down your mouse button and drag it to the trash icon on your dock.. drop it into the trash, empty the trash. Or you can control click on the folder and select "Move to Trash"

Okay - did that a couple of times now...
But now I see that sometimes there are still files left of that application in other folders (library/application support/....). So if you install / remove a lot of programs (e.g. for testing purposes) your system gets kindof 'dirty' after a while from all the small files that are still there from uninstalled software....

This is true and this is one of the complaints that people have with Mac, not just OS X, throughout the years. They really do need an uninstaller, but for some reason they refuse to create one Anyways if you really want to clean it out, do like you said, go to Library/Application support, library/preferences etc and clean out the files that you do not have applications for anymore.

Hi
I clicked and dragged the icon off the dock and it jumps right back into dock---now what?

As far as leaving bits and pieces in your library, there's no harm done. No other application is going to go reading the wrong preferences. They all have distinctly different names. And for the Applications Support folder, those are also only used by the specific application. Yes, they do take up disk space... but last time I checked, my Application Support folder was 15 MB, and Preferences was 7 MB. I don't think that's cause for alarm.
